We are very pleased at Objectif Libre to intoduce CloudKitty, an effort 
to provide a fully OpenSource Rating-as-a-Service component in 

Following a first POC presented during the last summit in Atlanta to 
some Ceilometer devs (thanks again Julien Danjou for your great support 
!), we continued our effort to create a real service for rating. Today 
we are happy to share it with you all.

So what do we propose in CloudKitty?
  - a service for collecting metrics (using Ceilometer API)
  - a modular rating architecture to enable/disable modules and create 
your own rules on-the-fly, allowing you to use the rating patterns you 
  - an API to interact with the whole environment from core components 
to every rating module
  - a Horizon integration to allow configuration of the rating modules 
and display of pricing information in "real time" during instance 
  - a CLI client to access this information and easily configure 

Technically we are using all the elements that are used in the various 
OpenStack projects like olso, stevedore, pecan...
CloudKitty is highly modular and allows integration / developement of 
third party collection and rating modules and output formats.

A roadmap is available on the project wiki page (the link is at the end 
of this email), but we are clearly hoping to have some feedback and 
ideas on how to improve the project and reach a tighter integration with 

The project source code is available at 
More stuff will be available on stackforge as soon as the reviews get 
validated like python-cloudkittyclient and cloudkitty-dashboard, so stay 

The project's wiki page (https://wiki.openstack.org/wiki/CloudKitty) 
provides more information, and you can reach us via irc on freenode: 
#cloudkitty. Developper's documentation is on its way to readthedocs 

We plan to present CloudKitty in detail during the Paris Summit, but we 
would love to hear from you sooner...
